GN Solids control is a leading manufacturing on drilling waste hazardous material transfer. GN offers turnkey solution for different hazardous waste generated from oil field.
Below are some major equipment popularly for drilling waste handling.
Item 1: Drilling waste mud and cuttings container

Drilling waste cuttings container

1)    The drilling cuttings can be used to collect cuttings from solids control equipment: shale shaker, mud cleaner, desander, desilter and centrifuge, and move to drilling cuttings treatment system for process.
2)    The container can be used to collect drilling cuttings from vertical cuttings dryer, High G dryer, and drilling waste high speed centrifuge, and move to TDU or stabilization unit for treatment.
3)    The container can be used to store and take waste mud and cuttings from offshore platform and take to the onshore yard waste management system for treatment.
4)    The top cover sealing type drilling cuttings container can be used to store and handling hydrocarbon contaminated drill cuttings.
Item 2: Drilling cuttings stabilization unit

Drill cuttings Solidification unit

The GN drilling cuttings solidification or stabilization unit can be used as the final treatment of drilling cuttings or waste sludge. The stabilizer unit can be used after the drying treatment equipment, like vertical cuttings dryer, high G drying shaker, drilling waste big bowl or high speed decanter centrifuges.
Items 3: Drilling waste Vertical cuttings dryer
Vertical Cutting Dryer utilize centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl treat the drilling waste mud with cuttings and waste oil, the centrifugal force can be up 900RPM with G force to 420G or super high speed 1200RPM with G force 750G. Liquid is forced through the screen bowl openings, but the solids and cuttings will be removed by the angled flights attached to the cone, as the cones rotate slightly slower than the bowl. Tungsten carbide material protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation.

2 sets of waste management processing system has left GN Solids Control Beijing factory and was dispatched to Tianjin sea port. The 2 sets waste treatment system is for a client from MENA region. The client is very happy with GN turnkey solution in this field. They compared different processing technology and finally decided to put GN Solids Control in his honour.
The 2 sets waste management was designed to suitable for container shipment. It means every item of the 2 processing systems can be put into container for ocean shipment.
The complete set oily sludge separation system and sand washing system was out into 9 ea 40ft high container. They will arrive the client’s yard around 40 days.

Big bowl decanter centrifuge

What will the 2 sets waste management processing system be used for?
One set of the system we call it oily sludge processing system. It was used to treat the oily sludge waste with 20PCT solids and soil phase.
Main equipment of the oily sludge processing system: vacuum pump to transfer the raw material to treating system, High G drying shale shaker with deck sealing device, big bowl decanter centrifuge with high speed, chemical dosing system with the function of 3 types of chemical dosing, more importantly, there is an 3-phase separation system after above mentioned equipment. It is used to separate the water, oil and soil.
The second system is a sand washing system. It can be used to remove the high solids content oily waste. The no. 2 sand washing system is very similar to the no. 1 oily sludge separation system, but the processing technology is different. And there is no shale shaker and the transfer equipment is different.
Furthermore, GN Solids Control offered high quality drill cuttings container for the 2 systems. The cuttings and solids container is suitable for offshore application.
When the 2 waste processing systems arrive client’s jobsite, GN Solids Control will send engineers to help for the commissioning of the 2 systems. And also offer trainer to the client’s operators to help them know how to operator and systems and how to maintain each equipment.

Full hydraulic drive (FHD) centrifuge is widely used in oil and gas drilling field. It can be used in solids control system for barite recovery or fine solids separation. It can also be used in drilling cuttings treatment system. As the oil and gas drilling flied is normally hazardous. Especially in the desert in Middle East and Africa, it is very high temperature may over 55 C degrees. The normal motor drive recommended ambient temperature is max. 55 C degree.

A full hydraulic drive decanter centrifuge is components of below parts:
1)    Decanter centrifuge main body
2)    Hydraulic motor
3)    Hydraulic drive system
4)    Control system
The function of a full hydraulic drive (FHD) centrifuge?
A centrifuge with hydraulic drive is an interesting object from the fluid dynamics point of view. In order to achieve high efficiency, the hydraulic resistance of the inner, quickly rotating with the rotor, passages should be minimized. At the meanwhile the fluid should go through an area far away from the axis of rotation, where the centrifugal force is bigger. Nozzle efficiency is crucial. The air in the gap between the rotor and the centrifuge cover also moves, and the air friction makes a significant contribution. Jets from the nozzles might break down into a fine spray and hit the rotor, slowing it down. It is quite a challenging job to optimize the full hydraulic drive (FHD) centrifuge. But it must to be done.
Advantages of a full hydraulic drive (FHD) centrifuge for oil and gas drilling:
1)    Full hydraulic drive system to use in high temperature ambient for heavy mud with flexible bowl and differential speed.
2)    Durable & less maintenance. The centrifugal casting bowl from duplex stainless steel, Tungsten carbide tiles for screw protection, tungsten carbide inserts for mud distribution port and solids discharge port, SKF bearings to give the centrifuge maximum operation life with less maintenance.
3)    Heavy Duty. The torque gearbox is up to 4163 N.M for heavy mud separation.

Centrifuges are used for separating solid particles from the fluid of different density, for example for cleaning oil in drilling waste fluids. High rotation speed of the rotor creates large centrifugal forces, pulling heavier particles to the side of the rotor, where they stay until removed during a regular maintenance, or from where they are removed continuously by a special mechanism. Frequently, the rotor of the centrifuge is driven by a separate electric motor, or by a shaft from the car engine.

GN Solids Control, with a separate U.S. brand GN Solids America, is a professional manufacturer on different size of decanter centrifuges. The centrifuge size varies from 9 inch to big bowl 30 inch to meet the application of different field.
GN design and make both 2-phase decanter centrifuge and 3-phase centrifuge for industry separation.
What is a 2-phase separation decanter centrifuge?
2-phase separation decanter centrifuge can used to separate solids or soil from the solids liquid mixture. The final products are solids and liquid mixture. If the clients want to get separate oil and water, they will use an oil water separator after it.
What is a 3-phase separation centrifuge?
3-phase separation centrifuge is widely used for oil water separate. They can separate and get the 3 phase final products: oil, water and soil. For a better separation result, 3-phase centrifuge cannot allow high solids content. Normally it will be used after a decanter centrifuge. A 2-phase centrifuge will be used to reduce the mud weight first. And then the liquids transfer 3-phase centrifuge.
GN Solids Control makes and designs centrifuges per the specified tasks and application requirement. All material of GN brand centrifuges are only chosen from high standard and famous brands. GN Solids Control own the full line advanced centrifuge processing machines. All these ensure GN made centrifuges are with optimized performance.
Moreover, GN owns a branch for design PLC and electrical control system; this gives GN advantages in electrical components for measuring and control technology. The performance and availability of the decanter centrifuge or three-phase centrifuges are significantly improved by the control system.

Oil based mud is the most normal lubrication agent of offshore drilling rigs. During drilling activities, huge quality of oil base mud and oil based cuttings will be generated and come out together with the oil rigs. The sands and rocks come out together with the lubrication oil based mud will be covered with oily material, and it is Non hydrophilic. These oil base mud and oil based cuttings are hazardous and have very bad damage to the ground and environment. In order to reduce and avoid the oil base mud and oil based cuttings pollute environment, there should be a technology to inject the hazardous oil based mud and oil based cuttings to the suitable lay of the ground.
We call the technology of injecting hazardous oil based mud and oil based cuttings generated during drilling activities as drilling cuttings re-injection.

The environmental protection policy is more and more strict, The new policy regarding the zero discharge of offshore drilling in China marine area will come out very soon. The policy will bring new challenges to the drilling activities of offshore, so the drilling cuttings re-injection technology is imperative and necessary, especially in the Bohai area, drilling cuttings re-injection operation will be a must-be part of the drilling operation.
The drilling cuttings re-injection technology has been effective for many years in many countries, it is a mature technology rather than new.And it is proved that the drilling cuttings re-injection technology will not pollute the formation. As the injection ground layer is not a production layer, and it cannot break the cover to cause water pollution, and so on. The drilling cuttings re-injection technology is the most reasonable drilling waste disposal methods for remote offshore drilling rigs.
The core of the drilling cuttings re-injection technology m lies in the choice of the injection ground layer, to build the simulation of the joint and the system on the platform.

There are many different kinds of replacement shaker screens according to different shapes of the screen frame and material. Below is the most normal type shaker screen type we normally used:
1)    Hook type (hard hook) replacement screen. It is mainly for below type of shaker models:
Derrick 513 and 514 shaker and mud cleaner, Derrick 2000 or 48-30 shale shaker or mud cleaner.
2)    Frame type replacement screens. The frame screen is mainly for GN brand shale shaker and mud cleaner, Mongoose type shale shaker and mud cleaners, Cobra, King Cobra series shale shaker and mud cleaner. VSM-300 series shale shakers.
3)    Soft hook screen. It is a very old type screen model. Fewer shakers utilize the screen type. As the soft hook screen cannot last long time. Its quality is not good. But as its lower price, may some old shaker type still use it.

Tell from the materials, there are 2 types of frame screen: steel frame and composite material replacement screen.
Compared with steel frame screen, composite material screen can lost for a longer time, and it can be stocked for a longer time. Normally, the steel frame screen can only stock 1 or 2 years. If it stocks a longer time, the screen quality can be reduced, as the steel material cannot last long time even with suitable warehouse protection. But the composite material can last a longer time. You can stock the composite material for 4 or 5 years, if you do not need to use them. The reason is as the special design of the composite material screen. Inside of the composite screen, it is steel frame for reinforce. And then a special kind of plastic material to cover and fill the steel frame. As its complex production, the composite material price is higher than steel frame, but it can last a longer time.
GN Solids Control is a professional manufacturer for different models and type replacement screens. Welcome you contact GN group for more information of replacement shaker screen model.
